GAS HEATER.

"Application filed. April 16, 1927.. Serial l lo.

T 0 all 111110772, may concern:

Be it known that 1, Human R. llnnrniuar, a citizen of the United States. residing at Kalamazoo. county of Kalamazoo. State of Michigan, have invented certain new and useful Improvements in Gas .l-leaters. oi which the following is a specifimtion.

This invention relates to improvements in gas heaters.

The main object of this invention is to provide in a gas heater of the type shown in U. S. Letters Patent No. 1280740 issued to Alfred H. Humphrey, Qctober 8, 1918. an improved means for removably supporting the radiants.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is the preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

Fig. I is a front perspective view of a gas heater embodying the features of my invention.

Fig. II is an enlarged detail vertical section (in a line corresponding to line 2--2 of Fig.

Fig. III is an enlarged detail vertical secgion on a line corresponding to line 3-3 of ig. I.

In the drawing similar reference characters refer to similar parts throughout the several views. and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 designates the casing structure generally. As the details of this casing form no part of my present invention, I do not illustrate or describe such details herein.

Within the casing I arrange a Ineback 2 having an overhang 3 at the top. The foraminatedtubular radiating elements i which for convenience I designate as radiants, are mounted in front of the fireback with their upper ends below but adjacent to the overhang 3 thereof.

The radiants and the fireback are mounted on the supporting plate 5 mounted within the casing. The supporting plate has holes 6 with which the radiants are aligned, the

Specification of Lctters Patent.

Patented lFch. 3%,

burner tips 7 being aligned with these holes so as to deliver to the radiants. The radiants are provided with groove-iike recesses S in their tips. the grooves of the several adiants being aligned to receive the retaining rod ii. This retaining rod is in the structure illustrated bail shaped, its arms ii) being iournaled in the casing so that the, rod may be swung into and out of engagement with the groove-like recesses 8 the radiants, the rod swinging under the overhang as illustrated in Fig. lit.

With this arrangement the radiants are securely retained in place, the securing means hoiever, being arranged so that it is inconspicuous. and the faces of the radiants are unobstructed.

l have illustrated and described my improvements in only one of the several adaptations in which they are used comn'iercially. I believe however, that the disclosure made will enable those skilled in the artto embody or adapt my innirove ments as may be desired.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: I

1. in a gas heater. the combination of a casing open at the trout, a supporting plate mounted therein, a firehack arranged on said supporting plate. radiants arranged on said supporting plate in front of said fireback. said 'adiants having transverse aligned grooves in the tips thereof. and a, bail shaped retaining rod journaled in said casing to swing into and out of engagement with said grooves.

2. In a gas heater, the. coml'iination of a casing open at the front. a supporting plate mounted therein. a fireback arranged on said supporting plate. radiants arranged on said supporting plate in front of said firehack, said radiants having aligned recesses in the tips thereof. and a retaining rod engagw able with said grooves.

3. in a gas stove, the combination of a casing, of a fireback having an overhang at the top. radiants disposed in front of said. fireback, with their upper ends below but adjacent to said overhang. said radiants having aligned recesses in their upper ends. and a bail shaped retaining rod journaled in said casing to swing under said overhang into and out of engagement with said recesses in said radiants.

i. In a gas stove, the combination of a casing, of a fireback having an overhang at the top, radiants disposed in front of said fireback, with their upper ends below but adjacent to said overhang, said radiants havmg aligned recesses in their upper ends, and a retaining rod adjustable under said overhang into and out of engagement with said recesses in said radiants.

5. In a gas stove, the combination of a casing, of a fireback having an overhang at the top, .radiants disposed in front of said fireback, and having aligned recesses in their. upper ends, and a retaining rod engageable with said recesses in said radiants.
